Global Sensitivity Analysis (GSA)
Global sensitivity analysis is a family of methods that uses generated distributions to investigate how model variables contribute to the final results.
Activity Browser performs GSA using distributions generated by a Monte Carlo simulation for the reference flows. It repeats the stochastic simulations while fixing selected variables. Comparing the lower and upper bounds then indicates how strongly each fixed variable influences the model's overall variability.
Read the detailed explanation on the wiki.
The methods are described in a published scientific paper.
": "全局敏感性分析（GSA）
全局敏感性分析是一类利用生成的分布来研究模型变量如何影响最终结果的方法。
Activity Browser 使用蒙特卡洛模拟为参考流生成分布，并据此执行 GSA。分析会在固定所选变量的同时重复随机模拟；比较变量的上下界，可以判断各固定变量对模型总体变异性的影响程度。
这些方法在一篇已发表的科学论文中有详细介绍。
", + "Monte Carlo Analysis
Monte Carlo simulations generate stochastic samples from the uncertainty distributions defined in the LCA model and use them to estimate the expected result distribution for each reference flow.
In practical terms, the model can define uncertainty distributions for some or all parameters. The simulation repeatedly samples from those distributions, producing a final probability distribution that describes the expected variability of the reference-flow results.
Read more about Monte Carlo simulation on the wiki.
": "蒙特卡洛分析
蒙特卡洛模拟从 LCA 模型中定义的不确定性分布进行随机抽样，并据此估计各参考流的预期结果分布。
具体来说，可以为模型中的部分或全部参数定义不确定性分布。模拟会反复从这些分布中抽样，形成最终的概率分布，用于描述参考流结果的预期变异程度。
